AEROTECH EDU176_Ndrive_HL

Aerotechs Network Digital Linear Drive (Figure 1-1) (and PWM Ndrive CP, HP, MP,

and Nservo, Npaq) complement the Automation 3200 System. Connected via the IEEE

1394 (FireWire®) communication bus, these drives provide deterministic behavior, auto

identification, and easy software setup from the Nmotion SMC software controller.

Featuring a high-speed Harvard architecture DSP, the drives are linear for eliminating

EMI/RFI emissions and have fully digital current and servo loops providing up to an 8

kHz servo loop closure, 32 MHz line driver encoder data rate, and an optional Ethernet

port for access to third party networked I/O solutions. Additionally, one 18 bit analog

output and one 16 bit analog input is standard. The Ndrive HL also features an optional

on-board brake relay, programmable resolution multiplication up to x65.536. with a 200

kHz maximum amplified sine wave input frequency, and up to three-axis Position

Synchronized Outputs (laser firing). In addition, the use of the commercially standard

FireWire communication link makes integration to the Automation 3200 network plug-n

play easy.

This product is intended for light industrial manufacturing or laboratory use.

Feature Summary

• Software configurable for brush (torque/current and tachometer mode) and

brushless motor operation

• Bipolar 40 or 80 VDC bus power supply

• Fully isolated power stage

• 5 VDC, 500 mA user output power for encoder and Hall effect signals, etc.

• Two mounting orientations optimized for heat transfer or minimal panel space

utilization

• Full protection against the following failure modes:

1. Control supply under voltage

2. Continuous current overload

3. Power stage bias supply under-voltage

4. Power stage output short circuit (phase to phase and phase to ground)

5. DC bus over voltage

6. IGBT device over temperature sense

• Line driver square wave or analog sine wave quadrature encoder primary

position and velocity feedback

• Line driver square wave auxiliary quadrature encoder input or output for PSO

(laser firing), etc.

• 4 opto-isolated user outputs standard

• 6 opto-isolated user inputs standard, 2 of which are high speed

• 2 differential analog inputs (one standard and one available with the IOPSO

option)

• 2 analog inputs (one standard and one available with the IOPSO option)

The Ndrive HL consists of a power connection (motor power and input power), three

FireWire ports, an optional Ethernet connection, an RS-232/RS-422 connector, LED

indicator lamps and two D-style connectors for Auxiliary I/O (15 and 26 pin) and Motor

Feedback (25 pin). An IOPSO/-IOPSOH option is also available, shown below (J301

J303. TB301-TB305), which has connections for PSO, absolute encoder, SSI Net, analog

I/O, digital I/O, and user power. Refer to Figure 1-2 for locations.

Ndrive HL Block Diagram

The standard package includes the bus power supply that operates from standard AC line

voltage (100/115/208/230 factory configured). The power supply is included with the

standard package for off-line operation without the need for an isolation transformer.

Figure 1-3 is a functional diagram including options. In addition, a soft start circuit is

included to prevent high inrush currents.
